During the Vienna Design Week I showed objects to sit on from the last 25 years in the legendary 800sqm hall of the Semperdepot. Each visitor could take a seat on the objects and could choose one of them. A photo-studio was built up in a corner of the hall and I made pictures of the visitor sitting on his/her selected object. 2 months later I presented the book showing more than 300 ways (not) to sit on 60 chairs. The books also includes a big work-compendium, an interview, lots of work-in-progress material and last but not least two flipbooks with chairman in action.
